The ATMOS 41W all-in-one remote weather station is one of the world’s few truly wireless weather stations, and it’s the most affordable research-grade station in its class. It’s robust, reliable, and simple to use. All of the telemetry is enclosed with an integrated cell module. But that’s not even the best part. There is nothing on the market that is easier to install. Put it in a backpack, take it to your site, secure it to a post pointing North, and walk away. It's that easy to start broadcasting real-time data directly to the cloud.
The ATMOS 41W remote weather station measures 10 environmental variables, including solar radiation, precipitation, air temperature (min, max, average), barometric pressure, vapor pressure, relative humidity, wind speed, wind direction, maximum wind gust, and tilt. It takes our ultra-reliable ATMOS technology to the next level with a dual rain measurement for higher accuracy and extended range, making it one of the most robust rain gauges on the market. It combines a drop counter and a tipping spoon to ensure accurate measurements, and it's the only rain gauge available that can measure electrical conductivity. Now you can tell if you're measuring rainwater, irrigation water, or if the funnel is plugged with bird droppings. Not only that, we've improved the solar radiation, water vapor, air temperature, and wind measurement capabilities to be more compliant with various meteorological organization observation standards.
Forget complicated and costly. If you need a truly wireless, all-in-one, remote weather station that is incredibly simple to install, low maintenance, and can withstand harsh weather conditions, we ve got you covered. ATMOS 41W makes scientific-grade accuracy easy and affordable, So you can discover more- - and work less.
